Hi Henrik, Thanks for this, my values were defined as GAUGE but the problem was fixed by the patch submitted by Graham Nayler. This hobbit install is running a 4.3 snapshot from late 2007. See this mail for the referenced fix: http://www.hswn.dk/hobbiton/2008/09/msg00283.html After applying, I can confirm that values are coming into the database at every run so far. Now to finish the graph definition. :) Kind regards, Davíð Henrik Stoerner wrote:
Check the rrd file with "rrdtool info /path/to/rrdfile.rrd" and verify that the "ds" lines show up as GAUGE. It sounds like you might have created the rrd file using COUNTER (the default).

Hi all,
I'm trying to create a custom graph for hobbit but am having some problems.
I have a script doing SNMP probing and returning status messages to hobbit. I have another script that generates RRD definitions for hobbitd_rrd.
I've added the script to hobbit_rrd extra_scripts: [rrdstatus] ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg NEEDS hobbitd CMD hobbitd_channel --channel=status --log=$BBSERVERLOGS/rrd-status.log hobbitd_rrd --rrddir=$BBVAR/rr d --extra-script=/usr/lib/hobbit/server/ext/sensatronics-grapher.py --extra-tests=temp --debug
I've also made a graph definition in hobbitgraph.cgi (not really the finished definition, but I think it should work for testing): [temp] TITLE Sensatronics environment monitor YAXIS Measurement DEF:11=sensatronics.rrd:11:AVERAGE DEF:12=sensatronics.rrd:11:AVERAGE DEF:13=sensatronics.rrd:11:AVERAGE DEF:21=sensatronics.rrd:11:AVERAGE DEF:31=sensatronics.rrd:11:AVERAGE DEF:41=sensatronics.rrd:11:AVERAGE DEF:42=sensatronics.rrd:11:AVERAGE LINE2:11#00CCCC:value COMMENT:\n GPRINT:11:LAST: \: %5.1lf (cur) GPRINT:11:MAX: \: %5.1lf (max) GPRINT:11:MIN: \: %5.1lf (min) GPRINT:11:AVERAGE: \: %5.1lf (avg)\n
Now, the rrd file is created but only occasionally do I see values entered into it (I haven't seen a pattern - looking over the rrd generated over the weekend I see some values, sometimes 30 minutes apart, sometimes hours, but almost all the measurement points show NaN)
My script is being executed every 5 minutes.
Here is the output from rrd-status.log (with hobbitd_rrd run with --debug flag): 2008-09-29 14:03:37 Want msg 698, startpos 1151746, fillpos 1151746, endpos -1, usedbytes=0 , bufleft=425213 2008-09-29 14:03:38 hobbitd_rrd: Got message 698 @@status#698/tankar_hiti|1222697018.325994 |10.200.10.3||tankar_hiti|temp|1222698818|green||green|1222263717|0||0||0|0 2008-09-29 14:03:38 startpos 1152334, fillpos 1152334, endpos -1 2008-09-29 14:03:38 -> do_external(tankar_hiti, temp) 2008-09-29 14:03:38 000021108 : Saving msg to file /usr/lib/hobbit/server/tmp/rrd_msg_21108 2008-09-29 14:03:38 <- do_external(tankar_hiti, temp) 2008-09-29 14:03:38 Want msg 699, startpos 1152334, fillpos 1152334, endpos -1, usedbytes=0 , bufleft=424625 2008-09-29 14:03:38 000021108 : Calling helper script /usr/lib/hobbit/server/ext/sensatroni cs-grapher.py tankar_hiti temp /usr/lib/hobbit/server/tmp/rrd_msg_21108 2008-09-29 14:03:38 000021108 : Helper input 'DS:11:GAUGE:600:0:U' 2008-09-29 14:03:38 000021108 : Helper input 'DS:12:GAUGE:600:0:U' 2008-09-29 14:03:38 000021108 : Helper input 'DS:13:GAUGE:600:0:U' 2008-09-29 14:03:38 000021108 : Helper input 'DS:21:GAUGE:600:0:U' 2008-09-29 14:03:38 000021108 : Helper input 'DS:31:GAUGE:600:0:U' 2008-09-29 14:03:38 000021108 : Helper input 'DS:41:GAUGE:600:0:U' 2008-09-29 14:03:38 000021108 : Helper input 'DS:42:GAUGE:600:0:U' 2008-09-29 14:03:38 000021108 : Helper input 'sensatronics.rrd' 2008-09-29 14:03:38 000021108 : Helper input '7:62:4:21:27:24:16' 2008-09-29 14:03:38 000021108 : Unlinking temp file 2008-09-29 14:03:38 get_hobbitd_message: Interrupted
The 'get_hobbitd_message: Interrupted' message always appears after accepting input from my script.
Any ideas?
Kind regards,
